Police in Vancouver, British Columbia, say a human foot inside a running shoe has washed ashore, the latest in roughly a dozen such cases since 2007.
Police say the foot and leg bone were seen late Tuesday afternoon floating along the shore of Vancouver's False Creek.
Police so far have no theories about how the foot ended up in the water.
In the past four years, about a dozen feet encased in shoes have washed up on beaches near Vancouver, along the southern Georgia Strait and off Washington state.
Most of the remains are unidentified, although investigators said at least two of the feet belong to men who were reported missing.
In previous cases, police said it appeared the feet separated from bodies naturally in the water and foul play wasn't suspected.
According to The Vancouver Sun , all of the feet have been found in running shoes.
The grisly discoveries have sparked a rash of hoaxes, including reports of fake feet and, according to the Sun, animal bones.
In 2008, a forensic pathologist and an anthropologist determined bones found in a shoe were an animal paw inserted into the shoe with a sock and packed with dried seaweed.
